Abstract

<P>PROBLEM TO BE SOLVED: To measure the thickness of a bone in order to make an implant treatment successful even when the thickness of the cut peripheral bone is hardly grasped during an implant operation and a direction is not suitable for photographing with X-rays in the operation. <P>SOLUTION: An axis is put into a hole obtained by cutting the bone, so as to measure a distance with the outer side of the bone. That is, a vertical axis is inserted into the inner part of the cut bone so as to measure the distance with an apex. Thus, the thickness of the bone is measured by a jawbone thickness measuring instrument. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

本発明は歯科の顎骨内に埋入するインプラント治療の器具に関する。  The present invention relates to an implant treatment device for implantation in a dental jawbone.

従来、顎骨の厚みを計測するには、術前のＣＴや顎骨外側から計測で行われている。  Conventionally, in order to measure the thickness of the jawbone, measurement is performed from preoperative CT or from the outside of the jawbone.

インプラント治療とは、歯牙の欠損した部分に人工歯根を顎骨に埋入する治療である。骨に穴をドリルであけていくものである。細いドリルから３ｍｍ、４ｍｍ、５ｍｍと段階的に穴をひろげていく。その際側面の骨がうすくなり側面に穴があくと、失敗の原因になりうる。術前にはＣＴやＸ線写真等で診査するのだが、術中には周囲の顎骨の厚みが気になりながら切削することになる。  Implant treatment is treatment in which an artificial tooth root is embedded in a jawbone in a portion where a tooth is missing. Drill holes in bones. The holes are gradually expanded from a thin drill to 3mm, 4mm and 5mm. If the bones on the side are thin and there are holes on the side, it can cause failure. Prior to the operation, CT and radiographs are used for examination, but during the operation, cutting is performed with concern about the thickness of the surrounding jawbone.

なお、本願発明に関連する公知技術として次の特許文献１を挙げることができる。  In addition, the following patent document 1 can be mentioned as a well-known technique relevant to this invention.

特開平８−１９６５５０号  JP-A-8-196550

上述の如く、術前の診査等では、術中の骨の状態を把握しにくく、レントゲンによっても撮影できない方向である。確実に切削するためにもインプラント埋入を成功させるためにも、骨の厚みをいつでも把握できることが望ましい。  As described above, pre-examination examination and the like are difficult to grasp the state of the bone during the operation and cannot be photographed by X-rays. It is desirable to be able to grasp the bone thickness at any time for reliable cutting and for successful implant placement.

本発明は、術中の骨の厚みを各段階いつでも測定できることが特徴である。  The present invention is characterized in that the bone thickness during surgery can be measured at any stage.

上述の骨の厚みを把握するために、本発明は骨の内壁から外壁間の距離を計測できることが特徴である。  In order to grasp the thickness of the bone, the present invention is characterized in that the distance between the inner wall and the outer wall of the bone can be measured.

以上説明したように術前の診査に基づきインプラント術を行い本発明を用いれば術中にも確実に骨の状態を把握することができ、患者、術者共に安全かつ確実に骨の切削を行うことに有効である。  As explained above, implants can be performed based on preoperative examinations, and the present invention can be used to ascertain bone conditions reliably during surgery, and both patients and surgeons can safely and reliably cut bones. It is effective for.

以下、本発明を図面に基づき詳細に説明する。  Hereinafter, the present invention will be described in detail with reference to the drawings.

図１は本発明の２種類の図である。縦軸１と針２の取りつけ位置が異なるこの２種類により周囲の歯牙、舌、口唇をさけ上顎左右、下顎左右を計測することができる。  FIG. 1 shows two types of the present invention. By using these two types in which the vertical axis 1 and the mounting position of the needle 2 are different, it is possible to measure the left and right upper jaws and the left and right lower jaws by avoiding surrounding teeth, tongue and lips.

図２は本発明により計測している図である。  FIG. 2 is a diagram of measurement according to the present invention.

図１縦軸１の長さは２０ｍｍから２５ｍｍ程度で縦軸１と尖端３が接触した位置が０ｍｍ、目盛りは１０ｍｍ程度となる。把持部４は１０ｃｍから１５ｃｍ程度で操作しやすくなると考えられる。  The length of the vertical axis 1 in FIG. 1 is about 20 mm to 25 mm, the position where the vertical axis 1 and the tip 3 are in contact is 0 mm, and the scale is about 10 mm. It is considered that the grip portion 4 is easy to operate at about 10 cm to 15 cm.

以上、本発明の実施の形態及び実施例を説明したが、本発明の範囲はこれに限定されるものではない。例えば、インプラント治療で深く骨を切削するようになれば状況に応じて適宜選択されるものである。  As mentioned above, although embodiment and the Example of this invention were described, the scope of the present invention is not limited to this. For example, if bone is deeply cut by implant treatment, it is appropriately selected depending on the situation.

本発明は、歯科で使用する器材を製造、販売する産業分野、医療分野で利用することができる。  INDUSTRIAL APPLICABILITY The present invention can be used in the industrial field and the medical field in which equipment used in dentistry is manufactured and sold.
